Description

Technical Field

[0001] The invention belongs to the technical field of water volume monitoring, and in particular relates to a gear flow meter and a use method thereof. Background Art

[0002] Air conditioning cold water pipelines are widely arranged on board ships. The amount of air conditioning cold water is closely related to the cooling effect of the air conditioning fan. Since the air conditioning cooling water pipeline is long and tortuous, the flow resistance at the end of the pipeline is large. The end-user cold water amount cannot be accurately measured, which will make it difficult to regulate its cooling capacity. When the end-user cooling effect is poor, it will become extremely troublesome to troubleshoot the reasons for the equipment and system pipelines. At present, when measuring the water volume of the pipeline, most of them are installed on the pipeline. The end of the branch pipe is connected to a gear flowmeter, and the branch pipe flow is measured by the flowmeter. The functional relationship between the branch pipe flow and the main pipe flow is obtained through experiments.

[0003] When the gear flowmeter is installed with a branch pipe, multiple connecting bolts are required to connect to the flange of the gear flowmeter. This connection method needs to be tightened diagonally to be sealed. Installing multiple connecting bolts at the same time is laborious and has low installation efficiency. Summary of the invention

[0008] Preferably, a Z-shaped block is fixedly mounted on one side of the connecting frame, a screw rod is threadedly mounted on the Z-shaped block, a threaded hole is formed on the top of the sliding rod, and the threaded hole is matched with the screw rod.

[0011] Preferably, a group of threaded rods are rotatably installed on one side of the protective cover, and the group of threaded rods are respectively located on two arc-shaped shells. A threaded barrel is threadedly sleeved on each of the threaded rods. The threaded barrel located at the top is slidably connected to the slot on one side of the positioning rod, and a handle is fixedly installed on one end of the threaded rod located at the top.

[0012] Preferably, a holder is fixedly mounted on the inner wall of the arc-shaped shell, a block is slidably mounted on the two holders, the block is fixedly connected to the threaded cylinder located below, and a connecting gear is fixedly sleeved on the two threaded rods, and the two connecting gears are meshed with each other.

When the rectangular seat is rotated, the rotating rod and the one-way screw can be driven to rotate through the transmission action of the bevel gear, thereby driving the slider and the annular cylinder to move. When the rotating rod rotates, it also drives the connecting mechanism to operate, so that the driven gear rotates to drive the connecting cylinder and the rotating rod to rotate synchronously. At the same time, the driven gear on the connecting cylinder simultaneously drives the gear ring to rotate, thereby causing multiple connecting cylinders to rotate synchronously, so that the connecting mechanism drives the connecting bolts on the annular cylinder to rotate. When the annular cylinder drives the connecting bolts to contact the nuts, the rectangular seat continues to rotate. Since the connecting mechanism and the rotating rod rotate synchronously, multiple connecting bolts are simultaneously driven to rotate and tighten on the nuts.

[0017] Step 3: Turn the handle to rotate the upper threaded rod, and through the setting of the connecting gear, the two threaded rods are driven to rotate at the same time. When the upper threaded barrel slides to the right and slides into the slot on the positioning rod, the lower threaded barrel slides to the left, thereby driving the card block to slide, and the card block slides into the card seat to connect the two arc-shaped shells, so that it is firmly fixed on the gear flowmeter body.

[0018] Compared with the related art, the gear flow meter and the use method thereof provided by the present invention have the following beneficial effects:

[0019] Compared with the prior art, the gear flowmeter and its use method provided in the present invention simultaneously drive multiple connecting bolts to be installed on nuts through the installation mechanism, avoiding the tedious operation of tightening the connecting bolts one by one in the traditional connection method, greatly improving the installation efficiency. Since the installation mechanism can ensure that multiple connecting bolts are tightened evenly at the same time, the sealing of the flange connection is enhanced and the occurrence of leakage problems is prevented. By setting a protective mechanism, the installation mechanism is effectively protected from damage and its service life is extended.

[0020] In summary, the gear flowmeter and the use method thereof of the present invention simplifies the operation steps by simultaneously driving the installation and tightening of multiple bolts, thereby effectively improving the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides a gear flow meter, such as Figure 1-10 As shown, the gear flowmeter includes: a gear flowmeter body 3 arranged on the branch pipe 2 of the pipeline 1 for monitoring the flow of the branch pipe 2; a group of flanges 4 respectively installed on the branch pipe 2 and the gear flowmeter body 3, and a plurality of nuts 5 are fixedly installed on the flange 4 located on the branch pipe 2; a plurality of connecting bolts 6 are arranged on one side of the gear flowmeter body 3 for connecting the plurality of nuts 5; a mounting mechanism arranged on the gear flowmeter body 3 for simultaneously driving the plurality of connecting bolts 6 to be mounted on the plurality of nuts 5; and a protective mechanism arranged on the gear flowmeter body 3 for protecting the mounting mechanism.

[0035] In this embodiment, the gear flowmeter body 3 is connected to the branch pipe 2 through the flange 4, but the traditional connection method requires the use of multiple connecting bolts 6 to be tightened diagonally, which is laborious and inefficient. In order to improve this connection method, the present patent sets a mounting mechanism on one side of the gear flowmeter body 3, and the mounting mechanism can simultaneously drive multiple connecting bolts 6 to be installed in multiple nuts 5 on the flange 4 of the branch pipe 2. In this way, the installation and tightening of multiple connecting bolts 6 can be completed in one operation, which greatly improves the installation efficiency and sealing. At the same time, a protective mechanism is also set to protect the mounting mechanism to prevent it from being damaged during use. The flow of the branch pipe 2 is monitored through the gear flowmeter body 3, and the functional relationship between the flow of the branch pipe 2 and the flow of the main pipe of the pipeline 1 is obtained through experiments, thereby realizing indirect measurement and regulation of the main pipe flow. The installation mechanism simultaneously drives multiple connecting bolts 6 to be installed on the nuts 5, avoiding the cumbersome operation of tightening the connecting bolts 6 one by one in the traditional connection method, greatly improving the installation efficiency. Since the installation mechanism can ensure that multiple connecting bolts 6 are tightened evenly at the same time, the sealing performance of the flange 4 connection is enhanced, and the occurrence of leakage problems is prevented. By setting a protective mechanism, the installation mechanism is effectively protected from damage and its service life is extended.

[0036] In a further preferred embodiment of the present invention, the mounting mechanism includes: a support block 7 provided on one side of the gear flowmeter body 3; a rotating rod 8 rotatably mounted on the support block 7, one end of the rotating rod 8 being fixedly mounted with a one-way screw 9, one end of the one-way screw 9 being rotatably connected to the flange 4; a slider 10 threadedly sleeved on the one-way screw 9, a ring-shaped cylinder 11 being fixedly mounted on the top of the slider 10, and the ring-shaped cylinder 11 being rotatably connected to the connecting bolt 6; a rectangular seat 12 rotatably mounted on the support block 7; a group of bevel gears 13 fixedly mounted on the rectangular seat 12 and the rotating rod 8, respectively, and a group of bevel gears 13 are meshed with each other; a connecting mechanism provided on the rotating rod 8 and the gear flowmeter body 3 for simultaneously driving multiple connecting bolts 6 to rotate.

[0037] In this embodiment, when in use, first use an electric tightening gun to insert the output seat of the electric tightening gun into the rectangular seat 12, and then start the electric tightening gun to drive the rectangular seat 12 to rotate. When the rectangular seat 12 is rotated, the rotating rod 8 and the one-way screw 9 can be driven to rotate through the transmission effect of the bevel gear 13, thereby driving the slider 10 and the annular cylinder 11 to move. When the rotating rod 8 is rotating, it also drives the connecting mechanism to operate, so that the connecting mechanism drives the connecting bolt 6 in the annular cylinder 11 to rotate. When the annular cylinder 11 drives the connecting bolt 6 to contact the nut 5, the rectangular seat 12 continues to rotate. The rotating rod 8 rotates synchronously, thereby driving multiple connecting bolts 6 to rotate and tighten on the nuts 5 at the same time. The whole installation process is fast, stable and controllable. Through the coordinated use of the one-way screw 9 and the slider 10, and the transmission action of the bevel gear 13, multiple connecting bolts 6 can be installed and tightened quickly and synchronously, which not only greatly improves the installation efficiency, but also ensures the stability and reliability of the installation. Compared with the traditional method of manually tightening the connecting bolts 6 one by one, the installation mechanism of the present invention can complete the installation and tightening of multiple connecting bolts 6 by rotating the rectangular seat 12, which greatly simplifies the operation steps.

[0038] In a further preferred embodiment of the present invention, the connecting mechanism includes: a fixed block 14 provided on one side of the gear flowmeter body 3; a connecting cylinder 15 rotatably mounted on the fixed block 14; a sliding rod 16 slidably mounted on the connecting cylinder 15, one end of the sliding rod 16 is fixedly connected to the connecting bolt 6; a group of driven gears 17 respectively fixedly sleeved on the rotating rod 8 and the connecting cylinder 15, and a group of driven gears 17 are meshed with each other; a connecting frame 18 fixedly mounted on the top of the fixed block 14, a gear ring 19 is rotatably mounted on the connecting frame 18, and the gear ring 19 is meshed with the driven gear 17 located on the connecting cylinder 15.

[0039] In this embodiment, when in use, the rectangular seat 12 is first rotated to drive the rotating rod 8 and the one-way screw 9 to rotate, thereby driving the slider 10 and the annular cylinder 11 to move. When the rotating rod 8 is rotating, the driven gear 17 on the rotating rod 8 drives the driven gear 17 on the connecting cylinder 15 to rotate, thereby causing the connecting cylinder 15 to rotate synchronously with the rotating rod 8. When the driven gear 17 rotates, the gear ring 19 is driven to rotate at the same time, thereby causing multiple connecting cylinders 15 to rotate synchronously. When the annular cylinder 11 drives the connecting bolt 6 to contact the nut 5, the sliding rod 16 rotates the connecting bolt 6 and tightens it on the nut 5. Since the gear ring 19 is meshed with multiple driven gears 17, it can be simultaneously Driving multiple connecting bolts 6 to rotate realizes a fast and synchronous installation and tightening process. Through the design of the connecting mechanism, the fast and synchronous rotation and tightening of multiple connecting bolts 6 are realized, which not only improves the installation efficiency, but also ensures the synchronization and consistency of the installation. The coordinated use of the driven gear 17 and the ring gear 19 makes the transmission process more stable and reliable, and can ensure the smoothness and accuracy of the transmission even under heavy loads. Compared with the traditional method of manually tightening the connecting bolts 6 one by one, the connecting mechanism of the present invention can complete the synchronous rotation and tightening of multiple connecting bolts 6 by rotating the ring gear 19, which greatly simplifies the operation steps.

[0040] In a further preferred embodiment of the present invention, a Z-shaped block 20 is fixedly mounted on one side of the connecting frame 18 , a screw rod 21 is threadedly mounted on the Z-shaped block 20 , and a threaded hole is opened on the top of the sliding rod 16 , and the threaded hole is adapted to the screw rod 21 .

[0041] In this embodiment, when the position of the slide bar 16 needs to be adjusted, the user first removes the twist rod 21 from the Z-shaped block 20, and then slides the slide bar 16 to the desired position. When the slide bar 16 moves to the specified position, the twist rod 21 is threadedly installed on the Z-shaped block 20, and its thread is screwed into the threaded hole of the slide bar 16, thereby fixing the position of the slide bar 16. By designing the combination of the Z-shaped block 20, the twist rod 21 and the slide bar 16, the connecting bolt 6 can ensure that the slide bar 16 is stable in the specified position after installation, thereby ensuring that the connecting bolt 6 will not loosen.

[0042] In a further preferred embodiment of the present invention, the inner cavity of the connecting tube 15 and the sliding rod 16 are both arranged in a rectangular shape, and the Z-shaped block 20 is located above the sliding rod 16 .

[0043] In this embodiment, the slide rod 16 is designed to be rectangular in shape and matches the inner cavity of the connecting tube 15. This design ensures that the slide rod 16 can slide smoothly in the connecting tube 15 without generating unnecessary friction or resistance due to shape mismatch. In addition, the rectangular slide rod 16 also provides better guidance, making the connecting bolt 6 more precise and controllable during the sliding process. The rectangular design increases the contact area between the connecting tube 15 and the slide rod 16, thereby enhancing the stability of the entire structure. At the same time, the slide rod 16 can slide smoothly in the connecting tube 15, avoiding friction or resistance caused by shape mismatch. At the same time, the connecting tube 15 is rotated so that it is easy to drive the slide rod 16 to slide at the same time, ensuring that the slide rod 16 will not slip in the connecting tube 15. The rectangular slide rod 16 provides better guidance, making the sliding process more precise and controllable.

[0044] In a further preferred embodiment of the present invention, the protective mechanism includes: a positioning rod 22 fixedly mounted on the flange 4 and one side of the gear flowmeter body 3 respectively; a protective cover 23 slidably mounted on the positioning rod 22, the protective cover 23 is mounted on the mounting mechanism, and the protective cover 23 is composed of two arc-shaped shells.

[0045] In this embodiment, after the connecting bolts 6 are installed, the protective cover 23 is placed on the mounting mechanism, and then the protective cover 23 is slid to one side so that the protective cover 23 is slidably connected to the positioning rod 22, thereby positioning the protective cover 23 to ensure that it does not fall from the gear flowmeter body 3. By providing a closed protective space for the mounting mechanism, the protective cover 23 can effectively prevent the external environment from interfering with or damaging the mounting mechanism, thereby improving the stability of the equipment. The protective cover 23 can reduce the erosion of impurities such as dust and moisture on the mounting mechanism, thereby reducing the equipment failure rate and extending the service life.

[0046] In a further preferred embodiment of the present invention, a group of threaded rods 24 are rotatably installed on one side of the protective cover 23, and a group of the threaded rods 24 are respectively located on two arc-shaped shells, and a group of the threaded rods 24 are all threadedly sleeved with a threaded tube 25, and the threaded tube 25 located at the top is slidably connected to the groove on one side of the positioning rod 22, and a handle 26 is fixedly installed on one end of the threaded rod 24 located at the top.

[0047] The handle 26 is designed to allow the user to easily rotate the threaded rod 24, thereby easily adjusting the position of the threaded rod 25 on the threaded rod 24 and quickly fixing and releasing the protective cover 23.

[0048] In a further preferred embodiment of the present invention, a holder 27 is fixedly installed on the inner wall of the two arc-shaped shells, and a block 28 is slidably installed on the two holders 27. The block 28 is fixedly connected to the threaded tube 25 located below, and a connecting gear 29 is fixedly sleeved on the two threaded rods 24, and the two connecting gears 29 are meshed with each other.

[0049] In this embodiment, when it is necessary to connect the two arc-shaped shells, first, the upper threaded rod 24 is rotated by turning the handle 26, and the two threaded rods 24 are driven to rotate at the same time by the setting of the connecting gear 29. When the upper threaded cylinder 25 slides to the right and is slidably connected to the card slot on the positioning rod 22, the lower threaded cylinder 25 slides to the left, thereby driving the block 28 to slide, so that the block 28 slides into the card seat 27, and the two arc-shaped shells are connected to ensure that they are firmly fixed on the gear flowmeter body 3. Through the cooperation of the card seat 27 and the block 28, and the transmission effect of the connecting gear 29, the structural stability of the protective cover 23 is further enhanced, so that it can better adapt to different installation environments and requirements. Since the two threaded rods 24 are fixedly sleeved with meshing connecting gears 29, when one of the threaded rods 24 is rotated, the other threaded rod 24 will also rotate synchronously, thereby realizing the synchronous positioning function of the protective cover 23 and improving the operating efficiency.

[0050] In a further preferred embodiment of the present invention, a guide rod 30 is fixedly mounted on one side of the inner wall of the protective cover 23 , a guide block 31 is slidably sleeved on the guide rod 30 , and one side of the guide block 31 is fixedly connected to one side of the threaded barrel 25 .

[0051] In this embodiment, the design of the guide rod 30 ensures that the guide block 31 can slide stably along it, thereby further enhancing the structural stability and adjustment function of the protective cover 23. Through the cooperation of the guide rod 30 and the guide block 31, the structural stability of the protective cover 23 is further enhanced, and the stability and accuracy of the threaded barrel 25 during the movement are also ensured, thereby improving the adjustment accuracy and reliability of the protective cover 23.

[0052] The present invention also provides a method for using a gear flowmeter, comprising the following steps:

[0053] Step 1: When in use, first use an electric tightening gun to insert the output seat of the electric tightening gun into the rectangular seat 12, and then start the electric tightening gun to drive the rectangular seat 12 to rotate. When the rectangular seat 12 is rotated, the rotating rod 8 and the one-way screw 9 can be driven to rotate through the transmission action of the bevel gear 13, thereby driving the slider 10 and the annular cylinder 11 to move. When the rotating rod 8 rotates, it also drives the connecting mechanism to operate, so that the driven gear 17 rotates to drive the connecting cylinder 15 and the rotating rod 8 to rotate synchronously. At the same time, the driven gear 17 on the connecting cylinder 15 simultaneously drives the gear ring 19 to rotate, thereby causing multiple connecting cylinders 15 to rotate synchronously, so that the connecting mechanism drives the connecting bolts 6 on the annular cylinder 11 to rotate. When the annular cylinder 11 drives the connecting bolts 6 to contact the nuts 5, the rectangular seat 12 continues to rotate. Since the connecting mechanism rotates synchronously with the rotating rod 8, multiple connecting bolts 6 are driven to rotate and tightened on the nuts 5 at the same time. The entire installation process is fast, stable and controllable.

[0054] Step 2: After installing the connecting bolts 6, place the protective cover 23 on the mounting mechanism, then slide the protective cover 23 to one side so that the protective cover 23 is slidably connected to the positioning rod 22, thereby positioning the protective cover 23 to ensure that it does not fall off the gear flowmeter body 3;

[0055] Step 3: Then turn the handle 26 to rotate the upper threaded rod 24, and through the setting of the connecting gear 29, the two threaded rods 24 are driven to rotate at the same time. When the upper threaded cylinder 25 slides to the right and slides into the card slot on the positioning rod 22, the lower threaded cylinder 25 slides to the left, thereby driving the card block 28 to slide, so that the card block 28 slides into the card seat 27, and the two arc-shaped shells are connected to ensure that they are firmly on the gear flowmeter body 3;

[0056] Step 4: After the fluid enters the connecting pipe through the branch pipe 2, it is discharged into the filter cartridge 32. In the filter cartridge 32, the fluid is filtered by multiple V-shaped filter screens 35 to remove impurities therein. The filtered fluid then enters the flow meter body 3 for measurement. Since the filter screen 35 is slidably connected to the arc-shaped clamping plate 33, when the filter screen 35 is blocked or needs to be cleaned, the user can easily remove it from the filter cartridge 32 for replacement or cleaning.

[0057] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0058] In another embodiment of the present invention, the gear flowmeter body 3 also includes a filter cartridge 32 and a connecting pipe, the connecting pipe is fixedly connected to the flange 4, the filter cartridge 32 is fixedly connected to the connecting pipe, the filter cartridge 32 is located on one side of the main body of the gear flowmeter body 3, and a plurality of arc-shaped clamping plates 33 are fixedly installed on the bottom of the inner wall of the filter cartridge 32, a plurality of filter screens 35 for filtering impurities in the branch pipe 2 are arranged on the plurality of arc-shaped clamping plates 33, the plurality of filter screens 35 are arranged in a V-shape, and the plurality of filter screens 35 are slidably connected to the plurality of arc-shaped clamping plates 33.

[0059] In this embodiment, after the fluid enters the connecting pipe through the branch pipe 2, it is discharged into the filter cartridge 32. In the filter cartridge 32, the fluid is filtered by multiple V-shaped filter screens 35 to remove impurities therein. The filtered fluid then enters the flow meter body 3 for measurement. Since the filter screen 35 is slidably connected to the arc-shaped clamping plate 33, when the filter screen 35 is blocked or needs to be cleaned, the user can easily remove it from the filter cartridge 32 for replacement or cleaning to ensure the filtering effect. Through the design of the filter cartridge 32 and the filter screen 35, impurities in the fluid are effectively removed, and the interference of impurities on the measuring mechanism of the flow meter body 3 is reduced, thereby improving the measurement accuracy. The design of the filter cartridge 32 and the filter screen 35 protects the measuring mechanism of the flow meter body 3 from erosion by impurities and extends its service life. The design of the sliding connection between the filter screen 35 and the arc-shaped clamping plate 33 enables the filter screen 35 to be easily removed from the filter cartridge 32 for replacement or cleaning, thereby reducing maintenance costs and time. At the same time, the V-shaped design not only increases the filtering area of ​​the filter screen 35, but also improves the impurity retention efficiency.

[0060] In another embodiment of the present invention, a removable arc-shaped cover plate 34 is provided on the filter cartridge 32 , the inner wall of the arc-shaped cover plate 34 is fixedly connected to the plurality of filter screens 35 , a sealing strip 36 is sleeved on the arc-shaped cover plate 34 , and the sealing strip 36 is adapted to the arc-shaped notch of the filter cartridge 32 .

[0061] In this embodiment, when the filter screen 35 needs to be replaced or cleaned, the user can first remove the fixing bolts on the arc cover 34, and then remove the arc cover 34 together with the filter screen 35 thereon from the filter cartridge 32. Since the filter screen 35 is fixedly connected to the arc cover 34, they can be conveniently taken out and replaced as a whole. When the arc cover 34 is reinstalled, the sealing strip 36 will fit tightly on the arc-shaped notch of the filter cartridge 32 to ensure the sealing. By designing a detachable arc cover 34, the filter screen 35 can be conveniently installed or removed as a whole, thereby simplifying the replacement or cleaning process of the filter screen 35 and reducing maintenance costs and time. The design of the sealing strip 36 ensures the sealing between the arc cover 34 and the filter cartridge 32, prevents fluid leakage during the filtration process, and ensures the filtration effect and measurement accuracy.

[0062] In summary, compared with the related art, the gear flowmeter simplifies the operation steps by simultaneously driving the installation and tightening of multiple bolts 6, thereby effectively improving the installation efficiency.
